BUTTON.

SPECIFICATION forming part of Letters Patent No. 635,706, dated October 24, 1899.

Application filed August 18, 1899. Serial No. '72 7,640. (No model.)

To all whom it may concern:

Be it known that I, FRANKLIN R. WHITE, a citizen of the United States, and a resident of Waterbury, in the county of New Haven and State of Connecticut, have made and invented certain new and useful Improvements in Buttons, of which the following is a specification.

My invention relates to an improvement in buttons, and more particularly to that kind to or class thereof generally known and referred to as tack or rivet buttons, wherein the button proper is secured to cloth or fabric by means of a metal tack or fastener.

The object of the invention is to improve 1 5 upon the button patented to F. G. Neubert, July 19, 1898, No. 607,542, it having been found in the manufacture of such patented button that the dies employed for curling the lower edge of the button-die are in a short time partially destroyed by reason of the fact that a groove is worn therein, thereby preventing the proper curling of said edge. It has also been found that by reason of the excessive pressure required to effect a proper curling of the buttqn-die the forming-die is broken, and thereby wholly or partially destroyed, the average life of the forming-die being but three or four hours. Again, by reason of the circular shape of the blank from 0 which the button-die is formed, there is necessarily a great waste of material, and, further, the variation in the thickness of the metal occasions more or less variations in the length of the shell or partially-formed button- 5 die, the consequence being that if the shell be too long the opening in the finished buttondie is too much restricted, due to the excess of metal constituting the blank, and should the blank be too thin the opening in the fin- 4o ished die is apt to be too large. In my newlyinvented button I have overcome these objections by constructing the button-die from a square blank, effecting thereby a great saving in the material used in forming said 5 blanks. Again,when the button-die is formed from a blank square in shape, the shell or partially-formed button-die has a serrated edge, and hence should there be a slight variation in the thickness of the metal constituting the blank any excess of metal will be distributed around the serrated edge and not wholly upon the projecting points, thereby overcoming all danger of forming the opening in the button-die too small. Further, by the employment of a square blank there is less metal to be curled than in the case of a round blank, and this being so the great pressure required in the latter case is not necessary. Consequently the die is not so apt to break nor is the groove in the forming-(lie so apt to be formed.

My invention further consists in certain novel features of construction and combinations of parts, as will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of the square blank from which the button-die is formed. Fig. 2 is a sectional view of the shell or partially-formed buttondie. Fig. 3 is a sectional view of the forming-die containing the shell. Figs. 4 and 5 are sectional views of the shell with the lower edge partially curled. Fig. 6 is a bottom plan View of the finished button-die. Fig. 7 is a sectional view of the completed button-die taken on the line 7 7 of Fig. 6. Fig. 8 is a sectional view of the completed button-die taken on the line 8 8 of Fig. 6. Fig. 9 is a sectional view of a button containing the button-die; and Fig. 10 is a similar View thereof, showing the tack or fastener upset within the die.

Referring to the drawings, A represents a blank, square in shape, and formed of the proper thickness of any desired metal, the dimensions of this blank depending upon the desired size of the completed button-die. This blank in the formation of the button-die is drawn into the form of a shell B, as illustrated in Fig. 2, the corners b of the blank forming the points I) of the shell, the lower edge of said shell B being thus scalloped or serrated. The shell B is then inserted in a forming-die C, as illustrated in Fig. 3 of the drawings, wherein by means of the plunger D the shell is crowded down until the points 1) are curled inwardly and upwardly, as illustrated in Figs. 4 and 5, forming a seat or anchorage for the upset end ofthe tack or fastener E, as illustrated in Fig. 10, the space 1) within the dome of the completed die A being sufficient to nicely contain the upset metal of the said tack or fastener E, and thereby hold the latter firmly without the addition of any filler, as has sometimes heretofore been the case with other button-dies constructed for a similar purpose.

It will be understood from the foregoing that my present invention diifers from that shown and described in the Letters Patent above referred to in that by reason of the blank being formed square in shape the edge of the shell, instead of being straight, is serrated, and in converting the shell into the completed button-die the metal forming the teeth of the shell, or, in other words, the metal forming the four corners of the blank only, is curled or bent instead of the entire lower edge of the shell, as is the case when said die and shell are made from a blank circular in shape. This being the case much less pressure is required for bending or curling said corners of the blank, as there is much less metal to curl, and instead of thickening the metal, as in the former case, the metal forming the corners of the blank in the present instance is given room to spread, thus materially adding to the life of the forming-die and overcoming the danger of forming a groove in the latter, as before stated. In other words, in the former instance the lower edge of the button-die is curled upon itself and thickened, whereas in the present instance the teeth forming the lower serrated edge of the bu tton-die are curled and spread.

After the die has been completed, as shown in Figs. 7and 8, it isinserted in the depressed center G of abutton H, as illustrated in Figs. 9 and 10, and held therein by friction or other well-known means. In securing the button to the cloth the piercing end of the tack or fastener E is first driven through the material F and into the button-die, by means of which latter the piercing end of said fastener is curled or upset, as illustrated in Fig. 10, said upset end hearing or resting upon the curled points of the die and filling the space within said die above said curled points, thus securely fastening the button in place.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A button containing a die, said die being formed from a square blank, and having the corners thereof bent or curled inwardly forming a contracted chamber within said die, and a seat or anchorage for the upset end of a tack or fastener, substantially as described.

2. A button constructed with a depressed center, and a die located in said center, said die being constructed from a square blank having its four corners bent or curled inwardly for partially filling said die, and forming a seat or anchorage for the upset end of a tack or fastener, substantially as described.
